x264 HD Video Encoding
Simply put, it is a reproducible measure of how fast your machine can encode a short HD-quality video clip into a high quality x264 video file. It’s nice because everyone running it will use the same video clip and software. The video encoder (x264.exe) reports a fairly accurate internal benchmark (in frames per second) for each pass of the video encode and it also uses multi-core processors very efficiently. All these factors make this an ideal benchmark to compare different processors and systems to each other.
Benchmark Results: The first pass of the x264 HD Video Encoding benchmark is not very processor intensive and overall clock speed helped the Paladin XLC Phantom with the overclocked Intel core I7 930 stay much closer to the stock Intel Core I7 970. The second pass however, benefits from the additional cores of the Intel Core I7 970. The out of the box speeds of the Intel Core I7 970 are slower than the overclocked Intel Core I7 930 by ~300MHz but the additional cores gave us nearly 12 frames per second better performance. Once we increased the speed of the Intel Core I7 970 to the level 3 overclock, the performance gap increased to nearly 20 frames per second!
